Chrysler's A-833 4 speed manual transmissions

Chrysler's A-833 4 speed manual transmission was introduced in 1964. The first came out of the new plant in Syracuse, New York.

The A-833 was the toughest transmission of the muscle car era. Most would also say the A-833 had some of the best shifting out of all the transmissions of that era.

The 23-spline (non Hemi) version, was for the most part quiet.

There were three basic styles of synchronizers assemblies.

The first generation was used from 1964-1967.

The Second generation 1968-1970½ .

And the third generation 1970½ - up.

Generations 1 and 2  are narrow insert designs, while generation 3 is wider.

All 3 generations shifted very well, most would agree however generation 1 shifted the smoothest.

Also with the wide inserts of generation 3 this was a huge advantage in drag racing.

The A-833 transmission came with different configurations with different imput  shafts and tail housings depending on engine and body style. The earlier models can be identified by the cast iron case.Be sure to go to swap meets and most likely you can find what your looking for.

Chrysler A-833 available in two different lengths

The A-833 transmission was available in two different lengths.

The A-body and the F-body were short.

The B-body and E-body were long.

Coarse and fine pitch gears were used along with four different production ratios.

The three versions 1.small spline was used in all body styles and with all engines except 440 and 426 cubic inch hemi, which used 2.large splines.

The 3.overdrive version was introduced in 1975. All of the small spline drive pinions have 23 splines, the large have 18 splines.

1968 Dodge auto's and there clutches 8 cylinder vehicles

Three types of clutches are used on these models. The 9-1/2 inch clutch used on dart models, Equipped with the 273 cubic inch engine.

The 10 inch clutch used on coronet models equipped with the 273 cubic inch engine is similar to the semi-centrifugal, except that it does not use the six centrifugal rollers.

The semi-centrifugal type clutch used on 8-cylinder models with 318,340,383,440 cubic inch engines, combines the feature of low pedal effort with that of a clutch capable of transmitting the full torque of the engine.

Six centrifugal rollers are assembled between the pressure plate and cover. These rollers are provided to increase the normal load on the disc assembly at higher engine speeds. As the engine speed increases, the centrifugal force of the rollers causes them to act as wedges between the cover and pressure plate and exert greater force against the disc.
